Italian police are investigating a man who they believe killed his mother, chopped up her body and then prepared to eat her after they found pieces of her body grilling in the oven and boiling in a pot.

Lino Renzi, 45, lived with his 70-year-old mother, Maria Pia Guariglia, in Salerno, in Southern Italy, when police and firefighters were called to their apartment because a neighbor smelled gas, according to Gazzetta del Sud.

Upon entering the apartment, the authorities found most of Guariglia’s mutilated body in the bathroom but her foot was in the freezer, various pieces of her body were cooking on the stove and some of her entrails were found on a plate in the kitchen.

Renzi, meanwhile, was discovered laying naked on his bed and he didn’t say a word as they took him into custody, according to Corriere del Mezzogiorno.

Although an autopsy has not been performed, investigators on the scene determined that Guariglia had been dead two to three days when they found her body wedged between the toilet and a cabinet in the bathroom.

They also found evidence that Guariglia had been hit in the head and temple while they found various wounds over the rest of her body.

The suspected cannibal had been experiencing mental health problems and was undergoing treatment when he was released into his mother’s custody earlier this year. Police found bottles of prescription drugs scattered throughout the apartment.
